vielen Seiten bestrahlt werden.
Im besonderen ist das wichtig bei trübem Wasser. Die Bakterien setzen sich vorzugsweise an die die Trübung verursachenden Teilchen ; sitzt nun bei dem Vorbeifliessen eines solchen Teilchens die Bakterie an der dem LichteabgekehrtenSeite,so übt das Teilchen eine Schirm- wirkung aus, welche die bakterientötende Wirkung der ultravioletten Strahlen nicht zur Geltung kommen lässt.
Dies bietet immerhin Schwierigkeiten und ist wohl auch nur durch sehr komplizierte Einrichtungen mehr oder weniger erreicht worden.
Diese Einrichtungen entsprechen wohl dem Bedürfnis, kleine Mengen von Flüssigkeiten zu sterilisieren. Sobald es sich aber um grosse Quantitäten trüben Wassers handelt, versagen sie durch ungenügende Bestrahlung völlig, da bei schnellem Fliessen die Zeit zu kurz wird, damit von allen Seiten die Teilchen dem wirkenden Lichte ausgesetzt werden.
Durch Versuche hat der Frfinder nun festgestellt, dass grosse Flüssigkeitsmengen selbst bei grosser Geschwindigkeit dann völlig sterilisiert wurden, wenn man, wie dies nachstehend

irradiated from many sides.
This is especially important in cloudy water. The bacteria preferentially settle on the particles causing the clouding; If the bacterium is on the side facing away from the light when such a particle flows past, the particle exerts a shielding effect which does not allow the bactericidal effect of the ultraviolet rays to come into play.
After all, this presents difficulties and has probably only been more or less achieved by very complicated devices.
These facilities arguably meet the need to sterilize small quantities of liquids. As soon as large quantities of cloudy water are involved, however, they fail completely due to insufficient irradiation, since with rapid flow the time becomes too short for the particles to be exposed to the light from all sides.
The inventor has now established through experiments that large quantities of liquid, even at high speed, were then completely sterilized if, as follows
